java.lang.NullPointer.exception: group [PLZ HELP ME FIX THIS BUG... :( ]

This bug keeps happening over and over and over again... I have uninstalled McAfee and scanned my pc with windows defender and nothing works... There are no proxy servers connected and I have tried everything. Does anyone know how to fix it?
